(2-7i)(9+5i)
18+10i-81i-35i^2
The answer is 35i^2 - 71i +18
(5,y)(8,-1)
d = sqrt ((x2 - x1)^2 + (y2 - y1)^2)
d = sqrt ((8 - 5)^2 + (-1 - y)^2)
d = sqrt (3^2 + (-1 - 3)^2
d = sqrt (9 + (-4^2)
d = sqrt (9 + 16)
d = sqrt 25
d = 5
so ur points are : (5,-3)(8,-1)
Answer:
positive 2
Step-by-step explanation:
got to negative 2 and keep going where the line stops and that's your answer
7. tan º = o/a
tan 24 = 24/x
24*tan 24 = x
x= 53.904
8. tan º =o/a
tan 24= 24/x
24/tan 24 = x
x= 53.904
9. cos º = a/h
cos 34 = x/46
46*cos 34 = x
x=38.135
Answer:
a. y-axis
b. (0,7)
c.7
Step-by-step explanation:
y-intercept is basically the point where the line intersect y-axis.
x=0 on any point of y-axis
hope it helps... mark me brainliest, if u don't mind
